Short explanation

A vulnerability in Siemens SIMATIC WinCC products stems from insufficient database role permission restrictions, allowing an authenticated remote attacker to escalate privileges and execute arbitrary commands.

Why does it matter?

It allows an authenticated attacker with database access to escalate privileges and execute commands on the host system, potentially leading to a system compromise.

What should be done?

Show the technical text from the sources

A vulnerability has been identified in SIMATIC WinCC V7.5 (All versions), SIMATIC WinCC V8.0 (All versions < V8.0 Update 11), SIMATIC WinCC V8.1 (All versions < V8.1 Update 7). The affected application does not sufficiently restrict the permissions assigned to a database role. This could allow an authenticated remote attacker with database access to escalate privileges and execute arbitrary commands on the host system where SIMATIC WinCC is installed, potentially leading to a compromise of the system.
